How we compare: sides sorted from longest to shortest on both sides, so a 20 x 40 x 30 cm bag counts as 40 x 30 x 20 cm. An airline may measure in a fixed position (for example height x width x depth, or in its sizer) and may weigh the bag: the airline's official rule decides, not this page. In inches we use the airline's own inch figures where it publishes them, otherwise its centimetre figures (1 in = 2.54 cm). Where an airline publishes inches only, the centimetres shown with “≈” are our conversion.
